BUTTON FASTENING.

Application filed February This invention aims to provide an improved button fastening which securely grips the supporting fabric.

' The invention may be understood by reference to one illustrative embodiment shown on an enlarged scale in the accompanying drawings, in which:

Fig. 1 is a sectional elevation of a button secured to a fabric with the illustrative fastener.

Fig. 2 is a plan view of the fastener; and

Fig. 3 is an elevation of the same.

It is to be understood that'the illustrative form shown in the drawings is simply a preferred embodiment of the invention; and that in the following explanation of that specific form, the described details of structure and organization are merely exemplary.

The button 5 shown in Fig. 1 is of known construction, comprising a shell, an anvil plate within the shell, a locking cap, and a collet, and is secured upon fabric 6 by means of a fastener. The illustrative fastener comprises a head and button engaging means, herein represented by a single prong 8 whose point is upset by the anvil plate during the attaching operation.

The inner or fabric-engaging face of the head 7 has at least one, and preferably four protuberances or points 9, conveniently formed integrally with the head by the head-forming die and spaced symmetrically relative to the prong 8. As shown, these protuberances are best formed near the periphery of the head and best are so shaped that when the button is clinched to the garment, the protuberances will press into and grip the adjacent fabric without any tendency to cut or tear the fabric. When the protuberances are well spaced, as shown, from the attaching prong or prongsof the fastener, they provide a large fabric-gripping points.

ping area, thereby preventing the fastener from tearing orpulling through the fabric. It will be clear that the greater the area of fabric gripped by the fastener, the more iecure its hold on the garment is likely to e.

Obviously the present invention is not restricted to the particular embodiment thereof herein shown and described. Moreover, it is not indispensable thatwall the features of the invention be used conjointly since they may be employed advantageously in variouscombinations and subcombinations as defined in the claims.

Having described one embodiment of my invention I claim:

1. Button fastening means comprising in combination a. fastener having a cylindrical fastening prong and a head having a plurality of spaced fabric-gripping points which grip but do not pass through the fabric to which the fastener is applied, a button into which said prong enters and means for upsetting the prong of the fastener inside the button to attach the button, said button being free to rotate about the prong of the fastener but said fastener being held against rotation by said fabric-grip- 2. Button fastening means comprising in combination a fastener having a head with a plurality of spaced fabric-gripping pro-. jections on theinner side thereof, said projections being relatively short so as to grip the fabric without passing through it, a fastening prong on said head constructed and arranged to penetrate the fabric, a button in which said prong is secured, and means for allowing said button to turn about said fastener.

In testimony whereof, I have signed m name to this specification,

JOHN M. CLARK,
